We look at the division of 787972 by 91 
We want to figure out the number of times 787972 can be divided by 91.

On to step 1:
7 divided by 91 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 91

Advancing to step 2:
91 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (7) of the dividend behind the 78 and repeat the process: 787 / 91

Step 3:
91 can be fit into 787 8 times, resulting in a remainder of 59.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 59 after subtracting 728 from 787.
Grab the next digit (9) from the dividend, add it to 59, then carry on: 599 / 91

Going ahead to step 4:
91 can be fit into 599 6 times, resulting in a remainder of 53.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
The remainder is 53 after subtracting 546 from 599.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 91

Moving on to step 5:
537 divided by 91 is 5 with a remainder of 82.
Put 5 as the next digit of the answer. 
Result so far: 865.0
If we subtract 455 from 537, we get 82.
Fetch the next digit (2) from the dividend, attach it to 82 and continue: 822 / 91

Going ahead to step 6:
When dividing 822 by 91, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 8659.0
Subtract 819 from 822 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 91 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 8659.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
91 can be fit into 300 3 times, resulting in a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 8659.03
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
When dividing 270 by 91, we get 2 with a remainder of 88.
The next digit of our result is 2. 
Result so far: 8659.032
Subtract 182 from 270 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 10:
91 can be fit into 880 9 times, resulting in a remainder of 61.
The next digit of our result is 9. 
Result so far: 8659.0329
If we subtract 819 from 880, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 11:
91 goes into 610 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 8659.03296
Subtract 546 from 610 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
91 goes into 640 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 8659.032967
If we take 637 away from 640, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
91 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 8659.032967
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
300 divided by 91 is 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 8659.03296703
Subtracting 273 from 300 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 8659.03296703 with a balance of 2.7e-08.
